Manual operation: See " Display Level as Voltage of EMF - RF Level " on page 184
[:SOURce<hw>]:POWer[:LEVel][:IMMediate][:AMPLitude] <Amplitude>
Sets the RF level applied to the DUT.
Notes:
If specified, a level offset
[:SOURce<hw>]:POWer[:LEVel][:IMMediate]:
OFFSet
is included according to the formula:
Minimum level + OFFSet ... Maximum level + OFFSet
In addition to numerical values, you can increase or decrease the values step by step
with the
UP
and
DOWN
according to the step width defined with
[:SOURce<hw>]:
POWer:STEP[:INCRement]
.
The RF output is activated with
:OUTPut<hw>[:STATe]
on page 385 (RF ON / RF
OFF).
Parameters:
<Amplitude> Minimum level ... Maximum level
Determines the RF output level.
Range:
Minimum level to Maximum level
*RST: -30
Example: The keywords of this command are largely optional. Therefore,
both the long and short form of the command are shown.
SOUR:POW:LEV:IMM:AMPL 15
or
:POW 15
sets the RF level at output A to 15 dBm.
Manual operation: See " RF Level " on page 180
[:SOURce<hw>]:POWer[:LEVel][:IMMediate]:OFFSet <Offset>
Note: The level offset is also effective for level sweeps!
Specifies the constant level offset of a downstream attenuator/amplifier. If a level offset
is entered, the level entered with
:POWer
no longer corresponds to the RF output
level.
The following correlation applies:
POWer
= RF output level +
POWer:OFFSet
.
Entering a level offset does not change the RF output level, but rather the query value
of
:POWer
.
For more information, see Chapter 5.4.1.1, "RF level vs. RF output level" , on page 180.
Only dB is permitted as the unit here. The linear units (V, W, etc.) are not permitted.
